Application filed October 8, 1917. Serial No. 195,300.

To all whom it may concern:

Be it known that I, CHRISTOPHER A. GAR- vEY, a citizen of the UnitedStates of Amen ica, resident of Clayton, St. Louis county,

State of Missouri, have invented certain new and useful Improvements inBrushes, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to improvements in brushes, and more particularlyto means whereby a brush tip is adjustably secured to a tip holder.

been experience in adjusting such material to suit the user of thebrush, or to conipensate forthe wear to which the brush is subjected inservice. For example, fountain type known as marking usually include atip made of felt or other yielding absorbent material, and it isfrequently necessary, or desirable, to adjust the tip relative to itsholder.

(Inc of the objects of the present invention is to enable the brush tipto be easily adjusted, either into or out of its holder, so that theuser of the brushean adjust the tip in either direction. When the tip isshortbrushes,

ened by wearing away in'service, it can be advanced away from the tipholder, and if the adjustment is not entirely, satisfactory, the tip canbe very accurately adjusted in either direction to enable the user toobtain Another object is to firmly secure the adjustable tip in itsholder, so that it will not be accidentally pushed into or out of theholder when the brush is in'service.

With the foregoing and other objects in view the invention comprises thenovel construction, combination and arrangement of parts hereinaftermore specifically described and illustrated in the accompanying drawingswherein is shown the preferred embodiment of the invention; however, itis to be understood that the invention comprehends I changes, variationsand modifications which come within the scope ofv the claims hereuntoFigure I is a side elevation of a fountain Brush tips are necessarily 15made of'yielding material, and difiiculty has cylindrical rod.

Fig. II is an enlarged vertical section of the lower portion of thefountain brush.

Fig. III is a view similar to Fig. II,

showing the small outlet passagewaysat opposite sides of the brush tip.

Fig. IV is a transverse section taken on line IV-IV, Fig. III.

Fig. is an inverted plan view of the brush.

To illustrate the invention, I have shown a fountain brush adapted to beused like a pencil, in making signs, lettering boxes, pa per cartons,etc. 1 designates the reservoir for the ink, or other fluid, and 2designates a yielding brush tip arranged'in the outlet below thereservoir.

A discharge device A, screwed into the lower portion of the reservoir,is provided I with a packing chamber 3, a relatively large passageway 4,and a tip. holder 5 screwed into the lower end of the passageway 4. Theliquid passing from the reservoir flows through a passageway 6 at theupper end of the discharge device, through the packing chamber 3 andhollow screw 7, to the large passageway 4, and'thence to the tip 2 inthe tip holder 5. The pac 'ng chamber?) may contain an expansible spring8- secured to a body of absorbent packing material which retards theflow of ink from the reservoir, as pointed out in Patent No. 1,182,554,issued to me May 9, 1916. However, it is to be understood that thepresent inventionis not in any way limited to a means for regulating orretarding the flow of ink from the reservoir to the tip. v

he tip holder 5 is preferably threaded internally as shown at 9, toprovide a spi- The brush tip 2 is made of yielding material, preferablytough fibrous absorbent material, such as felt, and it is preferably inthe form of an elongated, so closely fitted to the screw thread 9, thata corresponding thread is formed in the yielding material, as shown inFigs. II and III. It is to thread in the ielding tip can be readily Thisyielding brush tip is understood that the screw adj ust the tip 1neither direction. When the it will advance of the screw thread, thus tipis turned in one direction, longitudinally moving into the holder, andif turned in the opposite direction, the tip will advance-outwardly fromthe holder.

Obviously, the yielding tip can be very accurately adjusted in eitherdirection to enable the operator to obtain most satisfactory results. -Anew tip can be readily applied to the holder, and owing to the manner inwhich the tip meshes with the screw threads, it is securely interlockedwith the holder and will not, slip in either direction when the brush isin service. Y

The internal screw thread 9 is preferably mutilated, as shown at 10(Figs. llll and'lV) to provide relatively free outlet for the inkflowing from the reservoir to the lower end of the tip. The thread canbe mutilated by v merely slotting the charge device having a intern allyholder, as shown most clearly at 10 in Figs. 1 and V.

I claim 1. A fountain brush comprising a disdhargedevice provided withan'unrestricted outlet having an internal screw thread, and a yieldingbrush tip in the form of a cylindrical rod of fibrous absorbentmaterial, said rod being closely fitted to said internal screw threadand being movable longitudinally of said screw thread so that it may berotated and adjusted into or out of said outlet.

2.
